important safety precautions. They
mean:
Attention!
Personal Safety Is Involved!
Become Alert!
Obey The Message!
2.2 SIGNAL WORDS
The safety alert symbol is used in decals on the unit
and with proper operation procedures in this manual.
They alert you to the existence and relative degree of
hazards.
Understand the safety message. It contains important
information about personal safety on or near the unit.
2.3 NOTATIONS
NOTE: General reference information for proper oper-
ation and maintenance practices.
IMPORTANT: Specific procedures or information
required to prevent damage to unit or attachment.
2.4 PRACTICES AND LAWS
Practice usual and customary safe working
precautions, for the benefit of yourself and others.
Understand and follow all safety messages. Be alert to
unsafe conditions and the possibility of minor,
moderate, or serious injury or death. Learn applicable
rules and laws in your area.
2.5 REQUIRED OPERATOR TRAINING
Original purchaser of this unit was instructed by the
seller on safe and proper operation. If unit is to be used
by someone other than original purchaser; loaned,
rented or sold, ALWAYS provide this manual and any
needed safety training before operation.
2.6 PREPARATION
Before starting any removal of parts, proper
preparation is very important for efficient work. A clean
work area at the start of each job will allow you to
perform service repairs easily and quickly.
To reduce the incidence of misplaced tools or parts,
place removed components with all attaching hardware
in the disassembly order on a clean work surface.
Organization is a key part of proper reassembly.
Tools, instruments, and parts needed for the job should
be gathered before work is started. Interrupting a job to
locate tools or parts is a needless delay.
2.7 CLEANING AND STORAGE
IMPORTANT: Never spray unit with water or store unit
outdoors to help prevent sealed bearing rust or
corrosion. Water can seep into sealed bearings and
reduce component life. Bearings are sealed against dirt
and debris only.
A unit that is excessively dirty should be cleaned
before work starts. Cleaning will occasionally uncover
trouble sources. Dirt and abrasive dust reduce the
efficient work life of parts and can lead to costly
replacement.

IMPORTANT: If engine becomes "flooded" due to
tipping, clean air cleaner and remove spark plug, put
one teaspoon of oil in cylinder, turn engine over a few
times and reinstall spark plug.
4.3 FILLING THE FUEL TANK
To add fuel to fuel tank:
1. Put unit in open or well-ventilated area.
2. Stop engine and allow to cool.
3. Clean fuel cap and surrounding area to prevent
dust, dirt and debris from entering fuel tank.
4. Remove cap.
IMPORTANT: DO NOT use gasohol or gasoline
containing alcohol because alcohol will cause internal
parts to deteriorate. See Engine Manual for correct
type and grade of fuel.
5. Fill fuel tank. (See Specifications for tank capacity.)
6. Replace fuel cap and tighten.
7. ALWAYS clean up any spilled fuel.
4.4 GENERAL LUBRICATION
Swivel Lubrication (swivel units)
See Figure 4.
Apply Sten Mix Hi-Temp Grease or equivalent to the
lube fittings. Order P/N: 00036800 - 3 pack of 3 oz.
cartridges.
When using Sten Mix Grease for the first time, all
components should be thoroughly cleaned prior to
lubricating.
Commercial Models
Grease fittings on rear axle housing every 25 hours.
WARNING: ACCIDENTAL ENGINE START
UP can cause death or serious injury.
ALWAYS stop engine, remove key, wait for
moving parts to stop and remove wire from
spark plug before adjusting or servicing.
CAUTION: FUEL SPILLS may result in minor
or moderate injury and/or damage to the unit.
Before unit is tipped up onto housing, remove
enough fuel so that no spillage will occur.
Remove battery to prevent spillage of
electrolyte.
Figure 3 OM0210
WARNING: EXPLOSIVE VAPORS and its
FLAMMABLE FUEL can result in death or
serious injury. Handle fuel with care.
ALWAYS use an approved fuel container.
No Smoking! No lighted Materials!
No Open Flame!
Allow engine to cool before maintenance.
Gasoline is highly flammable and must be
handled with care. Allow engine to cool
several minutes before removing fuel tank
cap. Never fill tank when engine is running or
is hot from operation. DO NOT allow open
flame, matches, or smoking in area. DO NOT
overfill. Allow about 1/4" of tank space for fuel
expansion. Wipe up any spills and allow
vapors to dissipate before starting engine.
Use approved gasoline container.

4.5 CHECK MOWER BLADE
See Figures 5 and 6.
Regularly check mower blades for wear and that lock
washer is fully compressed by cap screw (requires
25-30 ft-lbs (33-40 Nm) of torque on cap screw).
When blade needs sharpening:
1. Block blade to prevent rotation.
2. Remove cap screw, lock washer and blade from
shaft.
3. Sharpen both ends of blade at original angle (25
o
),
removing equal amounts of material from each end
to maintain proper blade balance. New blades are
balanced to within 1.3 in. oz. at factory. DO NOT
grind around corner at tip of blade. If cutting edge
of blade cannot be sharpened in a straight line to
within 1/8 of an inch of its end, replace blade with
Ariens replacement blade only.
4. Install blade, lock washer and tighten cap screw
25-30 ft-lbs (33-40 Nm) until lock washer is fully
compressed.
IMPORTANT:
If mower is used under sandy soil
conditions, replace blades when air lifts become
eroded.
4.6 CHECK DRIVE BELT
Check drive belt for wear or damage. Replace belt if
worn or damaged.
4.7 CHECK ENGINE/BLADE CONTROL
The engine/blade control must stop the engine and
blade within 3 seconds after the bail is released. If the
engine or blade continues to run, adjust or repair
control immediately.
Engine control must stop engine ignition, at 3/4" to
1-1/4" from handlebar as control is released.

To check (Figure 7):
1. Start engine and slowly release control until engine
stops firing.
2. Measure distance between handlebar and control
at the point that engine stopped firing.
3. Turn cable nuts at handlebar mount clockwise if
measurement is more than 1-1/4" or counter-
clockwise if measurement is less than 3/4".
4. Turn nuts against mount to lock in position.
There must not be slack in cable.
To check, rotate blade in it’s cutting direction (this
draws control rod fully in).
To eliminate slack in cable, turn nuts on cable at
handlebar clockwise.
4.8 CHECK GRASS BAG
Check bag for wear or damage. Keep bag clean and
dry. Replace only with Ariens original equipment
replacement bag.
4.9 CHECK DRIVE CONTROL
Check operation of drive control. The drive must
disengage completely when the bail handle is
released. Adjust bail travel if necessary. See Figure 10.
When the wheel drive control is squeezed toward the
handlebar, the extension spring, located at the bottom
end of the traction cable, must start to extend when the
control is between 1-1/2" and 2" (3.8 and 5 cm) away
from the handlebar. To check:
1. Squeeze the wheel drive control toward the
handlebar until the spring starts to open.
2. Measure the distance between the wheel drive
control and handlebar at the handlebar indentation.
3. To obtain the proper adjustment, turn the cable
nuts. Turn clockwise if the measurement is more
than 2"; counterclockwise if the measurement is
less than 1-1/2". Tighten the nuts against the
bracket to lock in position. If there is not enough
thread length for adjustment, the opposite end of
the cable can be adjusted.
Three Speed Drive Control
When the wheel drive control bail is squeezed toward
the handlebar, the extension spring must start to
extend when the control bail is between 3-7/8" to 4-1/8"
away from the handlebar. The extension spring is
located at the bottom end of the traction control cable.

To check the control cable spring:
1. Squeeze the wheel drive control bail towards the
handlebar until the spring starts to open.
2. Measure the distance between the wheel drive bail
to the handlebar indentation.
3. To obtain the proper adjustments turn the control
cable nuts at the handlebar or the bottom of the
control cable anchor against the anchor supports.
4.10 HANDLEBAR ADJUSTMENT
Holes in handlebar braces provide four height
positions, a service position, and a storage position
(except on professional models).
Use one of the four holes to adjust handlebar height to
a safe, comfortable position. Place bolt on handlebar
bracket through one of holes 1, 2, 3 or 4 in order of
increasing height (See Figure 11).
NOTE: On Professional models nuts and bolts replace
pins.
For storage, rotate handlebar forward and place pins
through holes further up braces.
4.11 SPEED CONTROL BELL CRANK
The speed control bell crank holds the speed selector
rod in position after a speed has been set. The spring
washers may become loose with normal wear. If the
speed selector rod does not stay firmly in position,
adjust the speed control bell crank. See Figure 12.
To adjust:
1. Remove cover, fully compress the helical spring
lockwashers with lock nut and then back lock nut
off, one half turn.
2. If the speed selector rod is still too loose, tighten
lock nut by small increments until it holds its
position. Tightening the lock nut too much will not
allow the speed selector rod to move at all.
3. Align notch in left hand side of cover with bolt and
secure with knob.
